Yamaha outboard Prime Start !! How to fix it !! Part 1

Video is based on the Yamaha choke (PRIME START) and how to fix the most common issues

Dude, THANK YOU so much!! My Yamaha 50 TLR would start, hit low idle, then die. It was driving me nuts. After I saw your video, I replaced the diaphragm (41), both gaskets (42) since I was in the area, I figured I would put in a new set, and that dang O-Ring (40). My motor is a 2007 and that O-Ring was hard as a rock and shiny, it was actually hard to see because it took the shape of the Reed valve diaphragm thing it was on. As a matter of fact, the O-Ring broke getting it out. I put on the new O-Ring and put everything back together. Probably a 20 minute job. My engine starts and runs perfectly. The Prime Start hasn't worked this good since 2007 and I keep an extra O ring in my parts now if it ever acts up again. Thank you for helping me out!

Hello, i have a yamaha 60F 2 stroke and i thing i have more consumption than normal, not only on its way, also at idle . The engine has also difficult cold start(starts only with the red valve enrichment) so i am planning to change the o-ring and the solenoid to the prime start. The boat is ok (weight distribution, normal weight e.t.c.) . What should i do so i dismiss the idea of the more consumption? in my plans are also to put a new carburetor repair kit. Thanks a lot!

My yamaha 50 2004 has that problem... i guess they hired a laid off NASA rocket scientist to redesign the old tried and true manual choke and tried to make our lives easier?
